Abstract
The present investigation entitled “Varietal evaluation of Dahlia (Dahlia variabilis L.) under tarai conditions of Uttarakhand” was carried out at the Model Floriculture Centre, G.B Pant University of Agriculture and Technology, Pantnagar during 2019- 20. The experiment was laid out in complete randomized block design with three replications involving 10 genotypes. The aim of the experiment was to evaluate these ten different varieties of Dahlia on the basis of their growth and flowering parameters. Present findings revealed that among all the varieties of Dahlia cultivar Jishu showed highest plant height (113.22cm), plant spread (62.67 cm) and internodal distance (15.12 cm) whereas maximum number of leaves was found in cultivar Sohini (135.44). Matungini cultivar of Dahlia has maximum number of primary branches (10.11) and leaf diameter (11.78 cm). Maximum number of flowers per plant was observed in cultivar Matungini (14.78). Maximum flower diameter was recorded in the cultivar „Tenzin‟ i.e. 19.44 cm. The maximum fresh flower weight was observed in cultivar „Jishu‟ that was (55.90 gm). Maximum vase life was observed in the cultivar „Shanti‟ (6.6 days). It was observed from the experimental results that Jishu and Matungani variety was well suitable for cultivation in tarai regions of Uttarakhand during winter season period whereas the cultivar Kenya Yellow can be found well suited for pot culture purpose. The flowering in Kenya Yellow was very late as compared to all other cultivars. The plant height, number of branches and number of leaves were also found to be significantly correlated with the bud formation in the Dahlia plants. Overall performance of all the cultivars was the influence of its heritability and environmental conditions.
